【问题描述】：
我一直在尝试安装 psycopg2 以在 virtualenv 中使用。我设法发现它依赖于libpq-dev（因为 pip 给我一个Error: pg_config executable not found. 错误）可以使用apt-get install libpq-dev 安装。
但是，我安装libpq-dev 的所有尝试都导致了以下错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libpq-dev : Depends: libkrb5-dev but it is not going to be installed
E: Broken packages
谁能解决这个问题？
